Li-Fi’s Marketplace in the Future

Satish Parmar, Shubham Tharwan, Saurabh Pathak


In this work, we are describing our project on the Li-Fi system. The full form of Li-Fi is “light fidelity”. It is the forerunner of Wi-Fi. Li-Fi is a type of data transmission technology that will be used in the future because of its causes and benefits. Wi-Fi and Li-Fi are not similar to each other. There are many differences between them in every aspect. In terms of speed, Li-Fi is more than 50 times faster than Wi-Fi. According to my point of view, due to its speed and non-electromagnetic behavior, we get lots of advantages from it. The user of Li-Fi enjoys it at lower costs because of its lower energy consumption. Also, due to the fast speed of light, the transmission of data and information is 100 times faster than Wi-Fi. This hybrid network connects the high-speed data transmission of Li-Fi with the range of Wi-Fi. Visible light communication is used as a wireless communication technology. When Wi-Fi is active, a user can be transferred from one access point to another via a mobile connection without any loss. Li-Fi is a highly demanded technology compared to Wi-Fi in the future, but the problem is coverage area. The coverage area of Li-Fi is equal to one building area. When it is larger than a building, due to Li-speed, Fi’s the entire world uses it. The Li-Fi makes high-speed network connectivity with security devices using radiation of light. The user of Li-Fi enjoys heavy-speed connectivity on their system. The Li-Fi and Wi-Fi technologies are the same; both are used to share information without the use of any wire. In this technology, Li-Fi requires the following components for use in wireless sharing of data: (1) lamp driver, (2) LED lamp, (3) photodetector.
